Interaction of elastic waves with ice layer in shelf zone

A new absorbing layer for elastic waves

A new perfectly matched layer (PML) for the simulation of elastic waves in anisotropic media on an unbounded domain is constructed. Theoretical and numerical results, showing that the stability properties of the present layer are better than previously suggested layers, are presented. In addition, the layer can be formulated with fewer auxiliary variables than the split-field PML.

Waves and fetch in the Marginal Ice Zone

The technical approach is to use Surface Wave Instrument Floats with Tracking (SWIFT) buoys to measure waves, winds, and turbulence at the air-sea-ice interface (Thomson, 2012). The SWIFT deployments were successfully completed during the summer of 2014. These seasonal SWIFT measurements are placed in context using mutliyear subsurface Acoustic Wave And Current (AWAC) moorings and regional WAVE...

Interaction of hydro-elastic waves with a vertical wall

This study aims to gain knowledge on how hydroelastic waves interact with off-shore structures, for example off-shore wind turbines or oil rigs. The linear two-dimensional problem of hydroelastic waves reflected by a vertical wall is analysed. Water is of finite depth and is covered by ice. The fluid is assumed incompressible and inviscid. The ice sheet is assumed thin compared with both the wa...
